About the Original Mattress

Lull Original Mattress vs. latex foam mattresses
Can I remove my Original Lull Mattress cover?

We recommend that you do not remove your mattress cover unless instructed to do so by one of our Sleep Experts. Some Lull Mattresses utilize a fire retardant sock that contains small amounts of fiberglass, which makes the mattress fire retardant (the fiberglass allows us to sell a safe mattress without using harmful chemicals). The small amounts of fiberglass will not affect human health while sleeping, but you should not touch or place fabrics directly on the fire retardant sock.

Can I purchase a replacement cover?

Yes. Please call our customer support at 800-301-5845 and they will take care of everything.

Do Original Lull Mattresses off-gas harmful chemicals?

All foams used in Lull mattresses are CertiPUR-US Certified, which means that they meet rigorous standards for minimizing off-gassing. Our mattresses are made without harmful chemicals such as formaldehyde, ozone depleters, heavy metals and certain flame retardants that may cause cancer and genetic defects. All foams meet the standard of less than 0.5 parts per million VOC (volatile organic compounds).

Adjusting to your new Memory Foam Mattress

When switching mattresses, a break-in period where your body adjusts to the new support is common because the materials have not had time to soften and conform to your body.
It is recommended to try a memory foam bed for at least 30 days, and why the 365-night trial period is valuable.
The old mattress you've been sleeping on for years has adjusted to the shape and size of your body as well as your sleeping positions. After years of repeated use, materials compress and no longer adequately support your body. That indentation left by your body may cause sagging, reducing sleep quality.
A new pair of shoes often requires a breaking in period. The same principle applies to your new mattress; it may not feel comfortable until the materials have stretched and softened.
The break in period allows time for your body to adapt to your new mattress, but also for it to adjust to you. If your old sleeping surface was beginning to break down, your body might have over compensated to make you feel comfortable. A new sleeping surface means your body may have to readjust to the support of your new mattress.
